Is Yellow Schedule Safe to Use in 2026?
Generally Safe
Score 85/100Yellow Schedule has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The yellow-schedule plugin v1.1 exhibits a generally positive security posture, adhering to several best practices. The absence of known CVEs and the consistent use of prepared statements for SQL queries are strong indicators of a well-maintained and security-conscious development process. Furthermore, the plugin has no recorded vulnerabilities, suggesting a history of secure coding. However, the static analysis reveals some areas that warrant attention. The presence of unsanitized paths in taint analysis, even without critical or high severity flows, suggests potential for logic flaws or unintended behavior if these paths are exposed. Additionally, while the percentage of properly escaped output is high, the existence of 18% unescaped output presents a moderate risk of cross-site scripting (XSS) vulnerabilities. The complete lack of nonce and capability checks across all entry points, including the shortcode, is a significant concern, potentially allowing unauthorized actions or data manipulation by unauthenticated users.
Key Concerns
- Unsanitized taint flow paths detected
- Unescaped output detected (18% of total)
- No nonce checks on any entry points
- No capability checks on any entry points
